Gluco spikes can heavily impact hunger hormones, leading to erratic feelings of hunger if spikes occur frequently. Studies show that stable glucose levels result in more stable hunger hormones. Furthermore, in women, gluco spikes can cause insulin levels to rise, leading to an increase in testosterone production and hindering the conversion of testosterone into female hormones. This hormonal imbalance can result in symptoms of polycystic ovary syndrome. However, managing glucose levels can help reduce testosterone levels, regulate periods, and improve fertility in women with PCOS.
